## 概要
イベントコマンド「選択肢の表示」をクイズ形式っぽくします

## 使い方
1. プラグインコマンド「クイズ選択肢」を選択
2. イベントコマンド「文章の表示」で、問題を記載
3. イベントコマンド「選択肢の表示」で、選択肢を作成
4. 選択肢の正解かどうかで後続処理を自由に実装してください
5. プラグインコマンド「クイズ終了」を選択

@command quiz_choices
@text クイズ選択肢
@desc イベントコマンド「選択肢の表示」をクイズ形式に変更します
「選択肢の表示」を実施した次の「選択肢の表示」は通常になります

@command quiz_end
@text クイズ終了
@desc イベントコマンド「選択肢の表示」を通常に戻します
